High-efficiency open-weight and hosted reasoning AI powered by DeepSeek-V4 and R1 at ultra-low token costs.
Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
Learn languages with dual subtitles and a hover dictionary in any video
Watch with the subtitle of the language you are learning and your native language stacked, one line above the other, directly inside the video player.
Hover any subtitle word and the video pauses while a pop-up shows an AI-generated definition plus a translation of the surrounding context.
Every word you look up lands in your Wordbook with its original context, so you build a personal list from scenes you actually watched.
If an episode has no subtitles in your language, InterSub translates them on the fly with AI and shows the translation as the second line.
